[jboss-user] [EJB 3.0] - Re: UserTransactions and merge

[klaus_erber]

ok, thank you.

The transaction boundry was ok in my original code, but the first tip was the right one.

But there is another question. What about relationships like this:


  | UserTransaction ut = sessionContext.getUserTransaction();
  | ut.begin();
  | MyEntity a = em.find(MyEntity.class, Long.valueOf(1));
  | ut.commit();
  | 
  | ut = sessionContext.getUserTransaction();
  | ut.begin();
  | a.setName("FOO2");
  | MyRelatedBean b = a.getMyRelatedBean();
  | em.merge(a);
  | ut.commit();
  | 

Of course, that ends with a LazyInitializeException. But can I 'integrate' a bean in the transaction to use it as normal accessed (via find or Query) bean?

Greetings
Klaus
